Evaluation of the influence of production intensity in the field of dairy farming on the level of economic efficiency was performed using agricultural enterprises of the Region of Kharkiv and Chernihiv as examples. The enterprises were grouped according to the level of expenses per cow: up to UAH 10,000, UAH 10,000.1 - UAH 15,000, UAH 15,000.1 - 20,000, UAH 20,000.1 - 25,000 and more than UAH 25,000. It was established that production intensity in the field of dairy farming is very closely related with productivity of animals. In order to verify the significance of differences between groups under the parameter of cow productivity, comparison of the means by Student’s t-test was used that confirmed defi-niteness of this difference. Productivity of cows consistently increased from the first to the fifth group. It was determined that in absolute terms the largest difference was between the fourth and fifth groups of enterprises, which amounted to 1685 kg, and in relative terms - between the first and second - 37.0%. The regression model developed on the example of agricultural enterprises at the Region of Chernihiv allowed to determine influence and closeness of relationship between the level of prof-itability of milk production and independent indicators: productivity of cows (milk yield per 1 cow), the size of agricultural land, production cost of 1 quintal of milk and the share of milk in the structure of marketable products. The nonlinear nature of the relationship between the cost per cow and the level of profitability of milk production has been established. Based on the constructed model, it was determined that in the agricultural enterprises of the Region of Chernihiv at the average level of management in 2016 the highest cost efficiency level (16.1%) took place for the expendi-ture of 29174.6 UAH / head. At agricultural enterprises of the Region of Kharkiv, the highest cost efficiency level in 2018 (17.3 %) was reported for the expenditure of UAH 40,241/head. Key words: dairy farming, production performance, production intensity, cost efficiency, non-linear dependence of parameters, correlation model.

Background/Aim. The relationship between alcoholism and depression is observed in clinical trials. The factors which could predict persistence of secondary depression after alcohol withdrawal are not enough explored on admission. The differences between depressed (DA) and non-depressed (NDA) alcoholics regarding the degrees of severity of withdrawal, severity of depression and the intensity of cognitive dysfunctions were explored on admission to investigate possibility of prediction of the development of secondary depression in alcoholics. Methods. A group of primary male alcoholics (n=86) was recruited during inpatient treatment. After 4 weeks alcoholics were divided in the DA group (n=43) and NDA (n=43) group according to the score on the Hamilton Depression Rating Scale (HAM-D). Clinical assessment of withdrawal, scoring on the Alcohol Dependency Severity Scale- ASD, and scoring on the Mini Mental Scale-MMSE were performed in all the participants on admission. The differences between the groups were tested by the Student's t-test. Results. The DA group showed the significantly higher severity of depression, higher levels of alcohol withdrawal symptoms and cognitive dysfunctions than the NDA group on admission. Conclusion. The specific group of depressive alcoholics was shown to be characterized by the higher severity of alcoholism and depression on admission, which could predict prolonged, secondary depression. Early detection and concurrent therapy of secondary depression could improve the treatment, and reduce the relapse of alcoholism.

Abstract The aims of this study were: 1) to evaluate the sports potential of young basketball players; 2) to identify variables that discriminate sports potential assessed by coaches; 3) to verifythe relationship between classification of the multidimensional profile of athletes and classification of the sports potential by coaches. Sixty-two young basketball players aged 15.6±1.1 years from U-15 (n = 24) and U-17 (n = 38) categories participated in the study. A test battery was applied to evaluate sports potential indicators: 1) anthropometric; 2) physicomotor; 3) psychological;4) skills;5) socio-environmental;6) maturational and 7) sports potential.Clusteranalysis was performed in three groups: high, medium and low potential. Student’s t-test was used for the comparison between athletes evaluated by the coach as excellent and the others and the Chi-Square test to verify the relationship between sports potential classifications. It was observed that in the high-potential group, athletes were chronologically older, with higher % predicted adult height (PMS), competitive and determined sports orientation, higher body size, lower skinfold summation, and greater physicomotor performance. In comparison with other athletes, high-potential basketball players presented higher stature, wider wingspan,longer limb length, greater predicted adult stature and higher Z score of the % PMS. It could be concluded that the multidimensional approach was useful for the evaluation of the sports potential of young basketball players, requiring the use of multidimensional variables, in addition to coaches’ opinion regarding the potential of their athletes.

The Cost

The article aims at the evaluation and comparison of the structure of costs linked to the milk production in the Czech Republic and the Slovak Republic. The paper focuses on the potential of the cost controlling in agricultural production. The analysis is based on data from the comparable sample surveys of costs and yields of agricultural commodities carried out by the Institute of Agricultural Economics and Information, Prague, and the Research Institute of Agricultural and Food Economics, Bratislava, in the period 2007–2012. The authors apply the contribution margin calculation and the gross margin calculation. Using target costing, the upper limits of variable and fixed costs are set to reach the break-even point. One of the main finding is that the average costs per litre of milk are by 15.3% higher in Slovakia than in the Czech Republic. It is caused by a significantly lower milk yield in Slovakia. Cost controlling based on the knowledge about the structure of the average costs of milk production can help farmers to better manage their business.

This study analyses the relationship between the perfectionism dimensions, i.e. Self-Oriented Perfectionism-Critical (SOP-C) and Self-Oriented Perfectionism-Striving (SOP-S), and affect and the Big Five traits of personality in a sample of 804 Spanish students aged 8 to 11 (M  = 9.57; DE = 1.12). Student’s t test, Cohen’s d index and logistic regression analysis were used. The high SOP-C group scored significantly higher than their peers having low SOP-C on Negative Affect and Neuroticism, and lower on Positive Affect, Agreeableness, Consciousness and Openness to Experience. To the contrary, students with high SOP-S scored significantly higher on all adaptive dimensions (i.e. Positive Affect, Extraversion, Agreeableness, Consciousness and Openness to Experience), and lower on Negative Affect and Neuroticism. Effect sizes were small for most of statistically significant differences. These findings were also supported by regression analysis. Results are discussed in light of the debate on the adaptive or maladaptive nature of Self-Oriented Perfectionism.

Background/Aims: Peritoneal protein loss (PPL) is associated with cardiovascular disease and mortality in peritoneal dialysis (PD). Controversial results have been published about the effect of paricalcitol in PPL among PD patients. This study intends to analyze the relationship between paricalcitol and PPL in PD. Methods: In a retrospective study, prevalent PD patients were divided into 2 groups: “with paricalcitol” and “without paricalcitol”. X2-test, Student’s t test, Pearson correlation coefficient and Logistic Regression analysis were applied. Results: Eighty-two patients were included. PPL was lower among patients medicated with paricalcitol (5.17 ± 1.71 vs. 6.79 ± 2.10 g/24 h, p = 0.0001). In multivariate analysis, paricalcitol and dialysate/plasma ratio of creatinine (D/P creatinine) were independently related to PPL (OR 4.270 [1.437–12.684], p = 0.009 and OR 0.205 [0.064–0.659], p = 0.008, respectively), adjusted for diabetes. Conclusion: Paricalcitol and D/P creatinine were independently related to PPL. Paricalcitol may have an effect on PPL in PD patients

Food markets are becoming popular as new spaces for recreation, and this research aims to discover the motivations driving the tourists that visit these markets. Factorial analysis, cluster analysis and Student’s t-test were applied on 456 surveys from two food markets in Córdoba (Spain). Three motivational factors were obtained: Gastronomic experience and novelty; hedonism and leisure; and the relationship of the experience with work. Segmenting and analyzing the profile of the tourist may help economic agents develop new strategies for the tourism management of a destination and more accurate marketing and branding strategies that target specific customers with a niche message. The study could help develop products that align with tourists’ motives to increase satisfaction and loyalty.

This study aimed to establish the relationship between empathy and personality styles in medical students, considering the differences by gender. The participants were 278 students of the medical career of the Universidad del Azuay, Ecuador. They were evaluated using the Jefferson empathy scale and the Millon Index of Personality Styles. Relationships between empathy and personality styles were examined using Pearson's correlation coefficient and hierarchical multiple linear regression analysis, for comparisons by gender and educational levels; with both Student's t test and analysis of variance used respectively. Results indicated that the factor structure of the empathy scale is invariant between men and women, noticing gender differences in care with compassion and total empathy, with women presenting a higher mean. Differences are observed by educational level, where the general empathy in the first three years grows progressively, and then slightly decrease. In conclusion,  female students present a mean score of total empathy greater than men, with differences of empathy according to educational level

Summary Among many different definitions of competitiveness it is difficult to pinpoint the most appropriate one. In the paper it was defined as the ability to be profitable by effective use of available resources. The profitability ratios (ROS, ROA, ROE and value index) were proposed as measures of competitiveness and resources were indicated as one of the group of factors that has an impact on it. Precisely, the purpose of the paper was to examine the relationship between selected resourced based factors and competitiveness of agricultural enterprises. The study was done with the use of correlation analysis on the basis of statistical data on selected Polish companies operating in agriculture. The main finding was that the analyzed resources (the level of labour, size and quality of agricultural land and size of assets) were weakly correlated with competitiveness. This observation means that other factors have stronger impact on agricultural company’s competitiveness. They can refer to intangible resources (such as relational capital, know-how, managerial competencies, technological resources etc.) and external conditions (such as climate, legal issues) of agricultural enterprises.
